Minute fat particles present in lymph which normally are quickly cleared from the blood.

These are organized blobs of fats, synthesized in the submucosa of the small intestine out of dietary fats, phospholipids, specialized proteins and cholesterol, carried out of the intestinal tract by the lymph, and slowly released into the bloodstream. In the capillaries, the triglycerides inside the chylomicrons, recognized by their protein markers, are absorbed into the tissues for fuel or storage, and the outside cholesterol and phospholipid transport-cover continues through the blood to be absorbed by the liver for its use. This sideways approach takes (ideally) a large part of dietary fats into the lymph back alleys, spreading their release into the bloodstream out over many hours, thereby avoiding short-term blood fat and liver fat overload. To synthesize the maximum amount of dietary fats into chylomicrons, you need well-organized emulsification and digestion of lipids by the gallbladder and pancreas.

Chylomicrons are involved in fat absorption. They are free droplets containing fatty acids, some carbohydrate and some protein. They are released from absorptive cells in the intestine into the extracellular space, travel through the basal lamina into the intercellular CT spaces, enter the lymphatic capillaries and eventually reach the bloodstream via the thoracic duct.
